Did anybody else encounter this oddity?

I was up to date in Slackware64-Current as of Tue Dec 22 20:45:03 UTC 2020 & running 5.10.2 kernel

I did a clean install of VirtualBox testbuild VirtualBox 6.1.17 r141968 installer, built 2020-12-18T22:03:34Z.

In Plasma 5 I started VirtualBox and and it crashed giving the error:

Dec 23 09:05:01 kyiv kernel: [ 1597.888653] UINetworkReplyP[5487]: segfault at 10 ip 00007f591050a0c2 sp 00007f58ea5879a0 error 4 in libnm.so.0.1.0[7f59104d1000+a2000]
Dec 23 09:05:01 kyiv kernel: [ 1597.888666] Code: ff ff e9 54 ff ff ff 90 41 57 41 56 49 89 f6 41 55 41 89 fd 48 89 d7 41 54 55 53 48 81 ec d8 00 00 00 e8 31 b3 fc ff 49 89 c7 <8b> 40 10 85 c0 74 49 31 db 49 89 e4 66 90 89 d8 4c 89 f1 be c8 00

Funny thing is that rc.networkmanager was not enabled but gather something in either Plasma 5 or VirtualBox tried to access it.

Just in case there was corruption with the NetworkManager-1.28.0-x86_64-1 package, I downloaded it again and re-installed it. Same thing happened. I started rc.networkmanager, same thing.

Doing a "slackpkg remove NetworkManager-1.28.0-x86_64-1" allowed me to run VirtualBox with no issues.

What is it about libnm.so library that caused the issue? In essence it is just a wrapper for handling D-Bus.

So is it a VirtualBox issue or a Slackware64-Current issue?

A colleague of mine was running Slackware64-Current with the same VirtualBox testbuild & 5.10.2 kernel but with the NetworkManager-1.26.4-x86_64-1 package with no issues.

Yes, I encountered that segfault too -- when I was testing once more for https://www.virtualbox.org/ticket/20021 and https://www.virtualbox.org/ticket/20084
I resolved the problem but I do not remember how -- it was very late yesterday evening. Was it reinstalling the 141968 testbuild or installing 141967 development snapshot? Or was it installing the extension?
Sorry ...

I upgraded to VirtualBox-6.1.17-141968 from VirtualBox-6.1.16-140961

I am not encountering this. Launching VirtualBox from Plasma5 is normal.

I have rc.networkmanager enabled. In the spirit of testing, I disabled rc.networkmanager and reboot, VirtualBox still starts with no errors.

I had compiled a 5.4.85 kernel as a backup kernel for booting.

I re-installed NetworkManager-1.28.0-x86_64-1 and booted into 5.4.85 kernel. Started up Plasma 5 and tried starting VirtualBox testbuild VirtualBox 6.1.17 r141968 installer, built 2020-12-18T22:03:34Z.

It crashed with the 5.4.85 kernel & Slackware64-Current patched to & including the Tue Dec 22 20:45:03 UTC 2020 patches

Also I am running a Ryzen 5 system:

Motherboard:

Manufacturer: ASUSTeK COMPUTER INC.
Product Name: PRIME B450M-A
Version: Rev X.0x

CPU:

Socket Designation: AM4
Type: Central Processor
Family: Zen
Manufacturer: Advanced Micro Devices, Inc.
ID: 81 0F 81 00 FF FB 8B 17
Signature: Family 23, Model 24, Stepping 1
Version: AMD Ryzen 5 3400G with Radeon Vega Graphics

and 32 GB RAM

What appears to work as a "short term dirty" solution is removing the NetworkManager Package and running the 5.10.2 kernel.

I did an strace and got

bash-5.1$ strace -o out.log virtualbox
(process:8639): GLib-GObject-WARNING **: 12:45:10.571: cannot register existing type 'NMAgentManagerError'

(process:8639): GLib-GObject-WARNING **: 12:45:10.571: cannot retrieve class for invalid (unclassed) type '<invalid>'
Segmentation fault

Googled this and saw somebody else encountered this before:

https://www.linuxquestions.org/quest...lt-4175657749/

Okay, it appears I installed the testbuild [ VirtualBox-6.1.17-141968-Linux_amd64.run ] instead of the development build [ VirtualBox-6.1.97-141967-Linux_amd64.run ] and replaced the extensionpack with the development version and sure enough everything works perfectly fine.

My Bad.

I considered this resolved.

Yesterday I also face the same problem. I removed NetworkManager. And VirtualBox-6.1.16 is started running. This works for me.
